ELEARNING

Modern robotic crawlers provide a
means of safe and effective remote
data capture, reducing confined space
entries, minimizing data collection times,
enhancing inspection data quality, and
optimizing overall inspection spend.
Introduction
Direct visual testing (VT) is a nondestructive testing
method utilized for surface inspection and eval-
uation. The specifications of direct visual inspec-
tion are defined as placing the eye within 24 in.
(600 mm) of the surface to be examined, at an
angle of not less than 30°, supported by a white
light source with a minimum intensity of 100 fc
(1000 lux). For many industries, direct VT presents
formidable challenges, as the costs to access the
examination area are prohibitively expensive and
